Title: Remote control system
IPC: G08C19/12
Filed: 1965-01-11
Abstract: 1,091,371. Remote control systems. UNITED STATES STEEL CORPORATION. Jan. 11, 1965 [Jan. 10, 1964], No. 1211/65. Heading G4H. A remote control system for a motor comprises a wireless transmitting station including a variable frequency oscillator connected to a transmitter and a receiver connected with the motor to which is connected a detector and discriminator, the discriminator distinguishing the frequency of the signal and applying the frequency to a control panel for causing a movement of the motor proportionate to the frequency of the signal. In the embodiment described for controlling the bridge, hoist and trolley of a crane, potentiometers 18A, 22A, 18BA, 22BA, 18CA, 22CA (Fig. 1) in three oscillators 4A, 4B, 4C, are manually adjustable to control the speed and direction of rotation of the motors controlling the bridge, trolley and hoist respectively. To warn of the movement of the crane an operator closes switch 32D so that a fourth oscillator 4D applies a signal via audio amplifier 34 to an RF amplifier 52 where the signal is modulated on the carrier frequency which is generated by an oscillator 54 and transmitted through air waves by antenna 74. At the receiver this signal is picked up by antenna 26 (Fig. 2) and after conversion into a sine wave signal is applied to discriminators 226A, 226B, 226C, 226D. Since discriminator 226D is tuned to the frequency of oscillator 4D a relay coil 276 is energized which causes a bell 278 to ring. Switch 32A (Fig. 1) is then closed and the frequency signal from oscillator 4A transmitted in a similar manner to the discriminators at the receiver. Since discriminator 226A is tuned to the range of frequencies of oscillator 4A a signal is applied to servo amplifier 248A (Fig. 4) to drive a motor 338. This causes the motor to move the slide 342A of a potentiometer 342 until the potential developed by the variable resistor 342 balances the signal from the discriminator 226A when the motor 338 stops. The motor 338 also rotates an arm 344A so that when the motor stops the arm 344A rests on one of eight contacts to energize one of eight relays depending on which of the four possible speeds and which direction of movement was represented by the frequency from the oscillator 4A. On energization of the relay associated with the contact the motor controlling the bridge of the crane is driven at the correct speed and in the desired direction. When the bridge reaches its correct position switch 32A is opened by the operator. Frequency signals from oscillators 4B, 4C similarly control the motion of the trolley and hoist.

Title: Improvements relating to catalytic polymerisation
IPC: C08F18/04
Filed: 1944-01-24
Abstract: Water-insoluble vinyl esters or acrylic acid derivatives are polymerized in solution in a medium comprising a water-soluble volatile solvent for the polymer, diluted with water and containing not more than 0.05 per cent, by weight of the monomer, of hydrogen peroxide catalyst; optionally, the medium may also contain a plasticiser for the polymer.  Preferably, polymerization is carried out at 60-75 DEG  C. and the proportion of water is such that a second phase is obtained on reduction of the temperature.  The polymer is obtained in friable form by evaporation of the solvent, e.g. by feeding the reaction mixture to the nip of a pair of hot rolls, by precipitation by addition of water, or by spraying into a hot dry atmosphere.  Specified monomers are methyl methacrylate, ethyl acrylate, acrylonitrile and acrylic or alkyl-acrylic esters of allyl alcohol, methallyl alcohol or ethylidene glycol, and vinyl acetate.  Copolymers of two or more such monomers, or of one with divinyl ketone or di-isopropenyl ketone may also be produced. Specified solvents are acetone, methyl acetate ethylene-methylene ether and methylal. Plasticisers given include dibutyl, dimethyl and di-(methoxyethyl) phthalates, methyl phthalyl ethyl glycollate, tricresyl phosphate and tri-(monochlorethyl) phosphate. Specification 571,695 is referred to.

Title: Improvements relating to electric switches with temperature control, particularly for heating apparatus
IPC: H01H37/60
Filed: 1937-01-15
Abstract: 473,456. Thermal switches. EHRICH & GRAETZ AKT.-GES. Jan. 15, 1937, No. 1299. Convention date, May 15, 1936. [Class 38 (v)] In a thermally-tripped switch with a bimetal tripping mechanism, an oscillatable contact-carrying member is coupled through a spring subjected to a tensile stress with a switching lever rotatably connected therewith so that during the operating movements of the switching-lever the spring moves across a dead-centre position, the switching lever being connected by a spring to the base plate, the latter spring being tensioned during the " on switching movement so that a thermally-tripped pawl maintains the switching lever in the " on " position. As shown in the Figure, the operating lever e and contact-carrying lever a are pivoted on a common axis b and are interconnected by a dead-centre snap-action spring c. The lever e is also acted upon by a retractive spring g acting upon an arm h secured to the arm e, so that when the arm is rotated to the dotted position by a handle d the spring g is extended as shown. During this movement the line of action of the spring c is brought across the pivot b so that the contact arm a is brought rapidly into a position in which the pivoted contact bar o carried thereby bridges a pair of fixed contacts n. The arm e is automatically latched in its dotted position by a spring controlled latch f, one arm of the latch being under the control of a bimetallic strip m. On flexure of the latter due to a predetermined temperature rise in the controlled heating apparatus the latch is depressed and the arm e released and returned by the spring g to its initial position. During this return movement the spring c again crosses the pivotal centre of lever a so that this lever is rapidly returned to its initial position breaking the circuit between contacts n, n with a snap action.

Abstract: 101,815. Tully, C. B. Jan. 27, 1916. Producers.-In a plant in which coal-gas and water gas are manufactured by independent means from which the gases are withdrawn by a common exhauster, and wherein the water gas is made by a number of cyclically-operated generators the air and steam valves of which are mechanically controlled so that the period of gas generation of one generator overlaps that of other generators, the air and steam valves are operated by the motor producing the air blast. When the motor is a steam-engine, its exhaust furnishes the steam for the generators. In the arrangement shown, water gas from three generators A, B, C passes through valves a and a pipe b into the foul main c of a bench of coal-gas retorts, each generator being provided with a steam supply k, main and auxiliary air supplies e, f, and a snift valve o. The valve a and the steam valve m are opened, and the air valves e, r and the valve o are closed simultaneously, and vice versa, by a lever n above each generator, which is actuated by a cam 1, 2, or 3 on a shaft u driven from the) steamengine i, these cams being so arranged that two generators are delivering gas whilst the other is being blown. The air-supplying blower g is driven by the engine, from which exhaust steam is supplied to the generators through a valve w, pipe j, and hand-controlled valves y. Steam may be supplied from another source through a valve x<1>. Any generator may be put out of action by locking its lever n in the position shown in dotted lines in Fig. 2, and closing its valve y, the operating-rod of the valves e, r being disconnected to allow them to close. The air supply f is used when carburetted water gas is manufactured as described in Specification 15194/05.

Title: Coin freed prepayment mechanism for electricity meters
IPC: G07F15/00
Filed: 1928-01-19
Abstract: 308,401. Smith Meters, Ltd., Smith, E. W., Angold, H. E., and Angold, A. W. Jan. 19, 1928. Electricity, supplying by meter.-A switch of the contactor type is closed, under the control of a rotatable eccentric or disc, by a spring device the action of which is limited by a stop, the switch is held closed whilst electricity remains credited, and the switch is opened by spring means acting between the contacts. As shown in front and rear elevation in Figs. 2 and 3, the quantity wheel 5 is geared to a crediting cam 22 which is set forward after prepayment by one or more coins up to a limit determined by a device such as that described in Specification 308,558, and the cam is returned by gearing driven by the meter including a differential drive. The, switch, shown open in Fig. 3 and closed in Fig. 4, comprises a contact 17 on a spring arm 12 carried by a pivoted arm 11. The arm 11 is connected by a link 10 with a crank disc 8 on the spindle of a toothed pinion segment 6, Fig. 2, and is urged towards the open position by the spring 12 and by a light spring 21. A roller 24 on the crank disc 8 bears against a cam face 25 on a lever 23 so that the switch is held closed by the crediting cam 22 with the pinion segment 6 out of gear with the wheel 5 as shown in Fig. 5. When the flat 26 on the crediting cam releases the lever 23 the switch opens and the mechanism snaps over to the position shown in Fig. 3. The lever 23 is returned by gravity or by a light spring, and may have a knee joint to ensure return past the cam 22. The pinion segment 6 is now in the position shown in Fig. 2 and will be engaged by rotation of the quantity wheel whatever the angular position of the latter. On turning the quantity wheel with the switch open, the crank diso 8 is turned in the direction of the arrow, Fig. 3, and a roller 13 on the crank disc raises an arm 14 against the action of a spring 15 so that when the roller 13 passes the vertical dead centre, this spring snaps the switch to the closed position. The movement of the lever 14 is limited by a stop 20, so that friction between the lever 23 and the cam 22 is only that due to the light pressure of the springs 12, 21. The apparatus may be provided with a coin counter and credit dial, and with price-range adjustmentmechanism as described in Specification 308,557.
